That's the right modprobe info. It should work.

Run lsmod and see if there's another sound card driver that's being loaded 
first. If there is, rmmod the offending module.

My friend Chad wrote me a very small script which rmmods an ALSA driver that 
ALSA insists on inserting, and then modprobe in snd-cs4236 with that correct 
line.

The sound card is actually ISA, not PCI, so of course lspci wouldn't find it.

For some reason you have to go through this step *after* everything else 
loads. Don't ask me why, I have no clue.

Another thing: boot up while holding down F1 to get into the "hummingbird" 
BIOS. Check to see if "Fast Boot" is on or not. If it is, turn it off. Fast 
Boot is an optimization that only works with Windoze and is questionable even 
there. Turn off "Fast Boot" and you should have joy when you rmmod the bad 
module and modprobe in the good module.

Good luck and Goddess-speed,
Michelle
